Then you need to get involved in setting RIR policy because this concept of the fixed /48 network size is already starting to disappear. Nobody from the IETF was available to explain why the designers of IPv6 intended for /48 to be the fixed length network size when ARIN passed a policy to allow ISPs to allocate /56s to consumer customers. Even though the ARIN decision was not a bad one, unless better understanding of the IPv6 design is communicated, then the /48 boundary will fade away and everyone will have to renumber their networks when they change providers. --Michael Dillon -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
